摘要
为了考察菜单结构对语音菜单系统操作绩效的影响,研究设计了两种具有不同深度、广度的语音菜单结构,并比较两种不同的菜单结构下语音菜单系统操作绩效的差异。共有32名被试参加了实验,被试的操作任务是词语归类。研究结果表明:不同菜单结构对语音菜单系统操作绩效有着明显的影响。研究也进一步表明:语音菜单项数目一定时,适度提高菜单结构广度比增大深度更能提高系统绩效。
To demonstrate the effect of menu structure on auditory menu system, two kinds of auditory menu structure with different depth and span were designed to gain a greater understanding of menu structure. 32 participants took part in the experiment. Their task is to classify words. The result shows that different menu structure has significant effect on performance of auditory menu system. The result further shows that on condition that the number of menu structure＇ s item is invariable, enhancing the span can make the system much more effective than enhancing the depth can.
